IPC: G01R31/28
Filed: 1990-09-26
Abstract: PURPOSE:To shorten read time by placing two-layers of signal lines comprising control lines covering an entire IC chip and read lines in a matrix and placing MOS transistors in two stages at intersections. CONSTITUTION:In addition to inherent function circuits, two layers of signal lines comprising control lines 6 covering an entire IC chip and read lines 5 are placed in a matrix, while test elements 4 comprising two stages of MOS transistors are placed at their intersections.
